Abstract

A port ( 1 ) for a catheter comprises: a housing ( 10 ) having at least two fixing holes ( 120, 20 A, 120 B); a cavity ( 140 ) arranged in the housing ( 10 ) for receiving a fluid; a membrane ( 13 ) attached to the housing ( 10 ) and arranged on an opening ( 102 ) of the housing ( 10 ) for sealing the opening ( 102 ) such that the cavity ( 140 ) is enclosed in the housing ( 10 ) in a fluid-tight manner; and a catheter ( 2 ) connected to the housing ( 10 ), the catheter ( 2 ) being in fluid connection with the cavity ( 140 ). In addition a yarn guide device ( 16 ) is arranged on the housing ( 10 ) in between the membrane ( 13 ) and the catheter ( 2 ), the yarn guide device ( 16 ) comprising a guide channel ( 161 ) formed in the housing ( 10 ) for receiving a yarn ( 3 ) for fixing the port ( 1 ) to an object and for guiding the yarn ( 3 ) in between the membrane ( 13 ) and the catheter ( 2 ). In this way a port is provided which allows for an easy fixing of the port by means of a yarn and reduces the risk of the yarn interfering with the catheter attached to the port.

First claim

The invention claimed is:

1. A port for a catheter, comprising:
a housing,
a cavity arranged in the housing for receiving a fluid,
a membrane attached to the housing and arranged on an opening of the housing for sealing the opening such that the cavity is enclosed in the housing in a fluid-tight manner,
a catheter connected to the housing, the catheter being in fluid connection with the cavity, and
a yarn guide device arranged on the housing in between the membrane and the catheter, the yarn guide device comprising a guide channel formed in the housing for receiving a yarn for fixing the port to an object and for guiding the yarn in between the membrane and the catheter,
wherein the housing is formed by a first housing part and a second housing part, the first housing part forming said opening in which the membrane is received and the second housing part forming a base plate of the housing,
wherein a first group of fixing holes for receiving a yarn is formed in the base plate on a first side of the housing and a second group of fixing holes for receiving a yarn is formed in the base plate on a second side of the housing,
wherein the guide channel of the yarn guide device is formed as an indentation in the first housing part and extends from the first side to the second side of the housing.

2. The port according to claim 1 , characterized in that a yarn is placed in the guide channel of the yarn guide device.

3. The port according to claim 1 , characterized in that the catheter is fixed to a first end of the housing.

4. The port according to claim 1 , characterized in that the yarn guide device comprises an elevation bounding the guide channel towards the catheter.

5. The port according to claim 1 , characterized in that an insertion piece is arranged in the housing and forms the cavity.

6. The port according to claim 5 , characterized in that the membrane is attached to the insertion piece in a positive locking manner.
